This invention relates to improvements in snowplows, designed especially for clearing snow from highways, and has for its particular' object to provide a horse-drawn, snow remover, which is mounted upon bob-sleighs or runners, and is arranged to disperse the snow towards the opposite sidesof a roadway simultaneously. A further object is to provide an elongated frame, which is pivotally supported near its opposite ends by front and rear bobs. A further object is to provide similar 'ri ht and left hand lows, which aredispose at the opposite si es of the frame, the said plows'being secured to the frame by. chains or other, flexible means,

whereby, the plows may float and accommodate themselves to strains and inequalities the roadway; each 'plow comprising a mold-board, which is arranged at an oblique 2'0 angle to the linear dimension of the frame, the spread of'fthe said-inold-boards, being such as to plow orclear a path sufliciently broad to enable two vehicles to pass eaeh other. A further object is to provide means for adjusting the opposing plows, i. e. to raise a'nd'lower them for enabling the machine to be moved freely from place to place, as well as to pass over rocks and other obstructions that rise above the normal grade of the roadway. Anda further object is to generally improve and simplify the construction and operation of snow removers of the class. i

I attain these ob'ects the means set forth in the detaile description which follows, and as illustrated by the accompanying drawings, in which- Figure 1 is a top plan view of the com plete machine. F1g. 2 is a vertical cross- 40 section taken on line 22 of Fig. 1. Fig. 3 is a similar section taken on line 3-3 of Fig. 1. Fi 4 is a detached plan view of one of the oatingplows. Fig. 5 is a broken side elevation, taken in the direction of the arrow in Fig. 1, the left-hand plow being removed; and showing the ri ht-hand plow elevated. Fig. '6 is'a full si e elevation of the machine, showing the plows in the lowermost position. Fig. 7 is a top plan view of the front bob to which the auxiliary scraper is applied. And Fig. 8 is an end view of the scraper.

'In the drawings, 2 and 3 represent respectively the front and rear bobs, the runners .tache a series of of which are permanently connected by means of cross-beams 2 3 upon which are.

mounted bolsters 2'-3, the latter beingpivoted to the beams in the usual manner, by P1118113. The runners of the bob 2 pivotally support a tongue 2, the'rear end thereof being fitted with a cross-bar 2, whose oppo site ends are providedwith gudgeons that journal in loop-bearings 2, carried by the runners. The bar. 2 is provided with arearwardl extending-loo 2, to which are atexible draft rods or chains, as H, that connect respectively with the right and left hand plows.

55 represent elongated members-of the frame, whose front and rear ends are respectively supported by the bolsters 23,- and therefore tie the bobs 2 and 3 together; The

members 5 -5 are preferably disposed parallel and spaced from each other, andthe medial portions of said members are stiflened bymeans of similar reinforcing timbers or parts, as 5, which are secured by bolts 5. Midway between the bobs, upright posts 6--6' are rigidly secured to the outer edges of the frame members 5j5' by'bolts 6, and the said posts are respectively tied together and spaced near their top ends, by cross-bars 6. The the osts 6 and are fitted with notched plates 6, y which certain adjustments of the plows may be maintained.

77' represent respectively the rightand left hand plows, which are similar in conposts 6' are tallerthan' struction and operation. Each plow consists of a mold-board, as 8, preferably made of wood, and each mold-board preferably comprises. two sections, as 8'-8", which are 'oined end to end and rigidly held in lace ycleats 8", said parts being secured by Its,

as shown. The front surfaces of the mold boards are faced near their lower edges with sheet metal, as 8-8, the strips 8 being concave and comprising'the cutting orscraping edges that travel frictionally over the surface of the roadway. The mold-boards are preferably disposed at' an angle approximating 45 to the longitudinal dlmension of the machine, and said boards preferably inclineupwardly and rearwardly to facilitate the free movement of the snow. The moldboards 88 are supported by longitudmal members 9-9 which correspond toand perform the same function as the land of and loosely engage the lower end por tions of the posts .'6'6.:;.and arel'therefores,

free to move or float laterally, as well as vertically, during the plowing operations. The members 9-9 normally rest upon the roadway during the plowing? The plows are drawn forwardly .solely by therods or chains H, therear ends of whiclr'are re spectively connected to thelplows,by rncans of loops 7 the latter being secured "to l the moldboards and the members 91 (see F 1, 2 and The rear ends ofthemembers 9 arefiexi ly supported by chains 9, which are suspended from the ,rearends of the timbers 5. .jlhe plows 7, '7, may be lifted clear of; the. roadway independentlyfby means oft-levers 10'10, the latter being pivoted to the shorter posts, and their forward ends are connected to the members 99, by ,chainslO. Each lever 10 is fitted with, a latch 10, which is arranged "to engage the notches in the plates 6f. for hold ing the leversin various adjusted positions. In Fig. 5 the levers 10 are positioned horizontally for raising the plows clear of the roadway, as A. 1n Fig. dthe levers are 1 swung upwardly,w hich effectsthelowering of the plows'to the plowing position. It will be understood that when the machine is moving forward the angularity of the mold-boards 88 tends to force and hold the plows inwardly againstthe posts 6 -6", and that the relativelyshort chains 9f and 10 allow the plows to swing outwardly, lat erally sufficiently to preventcramping binding of the parts,- 6f represents guy,- chains. for connecting the tops of the posts 6' to the rear top portions of the "mold boards 8, to prevent undue spreading and straining of said portions,and for supplementing the flexible ,ties 9%:109- The plows 77 are normally spacedthe breadtlrof the frame and therefore may only remove the snow'at, either side of the center portionof thei roadwa To level or remove the more closely pac ed snow that. lies between the paths of the two plows, I provide anauxiliary scraper or'part consisting of a concave strip of sheet metal,as 12, which is arranged to be Y disposed angularly across the. runners of the front bob 2, as shown in Figs. 7 and-8. Thescraper 12 is provided with .a forked reach 12, whose, free end is formedwith a hook 12 which engages the loop 2" carried by the tongue, by which thescrapeis drawn forwardly. The scraper-is held, in itsangular position by rodsor chains12 of diiferent lengths, which maybe anchored to, a,hook 12 carried .by the .beam 2', the scraper 12 may be operated conjointly with the two plows as indicated in Fig. 1. The scraper Having thus escribedmyinvntion, what I claim, is- V 1. Inao snowigremover, the combination I with front and rear bob sleighs and a frame pi-voted at its opposite ends to the bobs, of

similar lows disposed at the opposite sides of the 'rardebetween said bobs, posts arranged in pairs secured to the opposite sides of saidfralile'a ainst which theland sides offtlie" lows bear, chains connecting the rear ends thefila'nd sides to'the frame, levers for raisingfand lowering the: plows relativel to itheframe'saidlevers belng pivoted to the forward pair 'ofposts, and chains con necting the forward ends of the levers to the forward'portions of thefplows.

' 2. a horse gamwn snowfremover, front and rear. bobffsleighs', an elongated frame conii'ectin'gv 5nd: spacing said bobs, similar plows disposedatthefo posite sides of the frame, the; land sides o the plows being arranged parallel to theffranie and looselyengaging dependingiportions of the frame, flexible means for connecting the rear ends of the landsi'des to the" frame, levers for raising and-loweringthe plows abovethe roadway pivotedjto the frame, flexiblemeans connectingsaidlevers with the forward ends of the land sides, and flexible means for separatelyiconnectingthe forward ends of the plows'o the front bob, for propelling said plows."

3.'In a snow remover for highways, the combination with front and rear'bob sleighs, of'a'j frame supported by and spacingsaid bobs, posts arranged in pairs sup' orted by the frame between the bobs, siini ar plows comprising molcbboards and land-sides dis- PQSed at the opposite sides of the frame and outside'of said posts, the land sides of the plows arranged to frictionall engage the lowerends of; the'posts, flexib e means connecting the rear e ds of the land sides to thefra'me, levers disposed arallel to the frame outside of the posts'for raisin the plows above the roadway, said levers eing pivoted to the forward pair of posts, locking means carried bythe rearmost posts and by said levers for maintaining the adjustments ofithe lows,.flexiblemeans connecting the forwar endsof the'leversto the correspondin}; portions of the land sides, draft means connecting-the'plows to the forward hob, and flexible. means for"connectin the 'rearmost plostslwithjthe moldboar'ds o the plow.

. 4. Inasnow remover for highways, front each plow loosely engaging the lower ends of the corresponding posts, theother arms comprising mold-boards arranged to disperse the snow laterally from the frame, means connecting the forward ends of the plows to the forward bobs for propelling the plows, means for flexibly connecting the rear portions of the plows to the corresponding sides of the frame whereby the plows may'move freely independently of the frame, levers for locking said levers in various adjusted positions. 7 a
